Film microstructure and kinetics of 2K WB coatings based on quaternary ammonium formation

This work describes an extensive study about the influence of polymer particle morphology of two component coating systems based on crosslinking via quaternary ammonium crosslink formation. The morphology of the polymer particles produced by emulsion polymerization was carefully designed to offer an enhanced pot-life, better stability, lower VOC among others, as compared to more traditional waterborne two component systems. Moreover, the influence of the particle morphology on the reactivity of the system was addressed using FITR techniques. Scanning electron microscope and atomic force microscope measurements were employed to study the film microstructure of the coatings produced with such systems. The analysis of the cross-section of the films revealed the importance of particle coalescence and polymer inter-diffusion on the occurrence of both physical and chemical crosslinking.

Phase-stepped deflectometry as a powerful tool to determine the appearance of paints and coatings

Phase-stepped deflectometry (PSD) is a relatively new, powerful and yet very affordable optical technique that can be used for the quantitative determination of the surface profile (appearance) of paints and coatings. With PSD several phase-stepped sinusoidal patterns are displayed on a computer screen which illuminates the surface under study and a camera is used to capture images of the reflected patterns. Analysis of these images allows quantitative determination of the surface profile. It will be shown that the correlation between PSD results and other methods used in the coating industry to evaluate appearance is generally very good. As PSD is a contactless and fast technique, it also allows determination of the appearance of wet layers and it can thus be used for the quantitative determination of sag and levelling phenomena in paints during drying and/or curing.

Structure/activity relationships of waterborne stain-blocking binder technologies

Universal stain blocking ability of tannin and other staining ingredients found in many wood substrates as well as dyes and markers remains a substantial challenge for waterborne primers. Apart from a baseline of strong stain-blocking performance, waterborne primer systems also need to fulfill further important criteria like good adhesion properties to various substrates, sand-ability, excellent hiding power, early recoat-ability and extended outdoor durability, just to name a few examples.
The presented work focuses on comparison of various waterborne binder technologies, including but not limited to cationic, anionic, zwitter-ionic and multi-domain binder concepts and their overall performance profiles in stain-blocking primer applications. Structure/activity relationships with respect to universal blocking performance will be outlined and discussed.

NISO goes water

Two big trends are constantly driving innovation and product development in the coatings industry: the continuous trend to reduce volatile organic compounds (VOC) in all fields of organic coatings and the increasing concern about the negative health effects of harmful and toxic components in coating formulations. Solvent borne 2-pack binders based on isocyanate crosslinkers are the industrial standard technology for high performance ambient to low bake coatings on metal, wood and plastic substrates. The conversion to 2-pack waterborne systems has mainly been limited by the blistering stemming from the reaction of isocyanates with water. Hence a waterbased non isocyanate crosslinking system is presented which yields high performing coating formulations with very low VOC content. Due to the absence of isocyanate crosslinkers health hazards are minimized and no blistering is observed even at high film build.

Novel bio-based energy-curable PU dispersions

Novel bio-based energy-curable polyurethane dispersions are delivering superior coating performance with a favorable ecological footprint. They address today's market demand for sustainable products in the perspective of a tri-dimensional model inspired by Life Cycle Analysis. Chemical innovation involves a structural approach towards new polymers with increasing bio-carbon contents that keep very high reactivity and immediate hardness after cure. This methodology guarantees a defined level of bio-carbon content according to ASTM D6866 standard. The new low-viscous products offer robust spray application with an attractive performance as a wood topcoat combining excellent mechanical & chemical resistances. More than ever, allnex is building on an environmentally-friendly product range and is painting coating innovation in green for a great sustainable future.

Greener evolution of Powder Coating Resins technology

Powder coating is a well recognise environmental friendly technology if compared with other coating solutions like liquid coatings for instance. Recently the introduction of more strict SHE regulations and the market requirement of respecting specific ecological regulations have had an important impact for the Powder Coating technology in the direction of developing greener and more sustainable solutions. Our company dedicated important efforts to satisfy those new requirements in direction of using recycled products or avoiding specific raw materials with high environmental impact while keeping high coating resin performance. The objective of this presentation is to present the findings of allnex to make powder coating technology greener. Click here to register.
